Offset for change vehicle handling?

[0xNull]

Hello! I'm trying to change at least one of the characteristics of the car. 

I found this offset:

0xC2B9DC - The beginning of the Handling block. Each slot has 224 bytes of data.

• +0x0 = [dword] Index / Identifier
  
• +0x4 = fMass
  
• +0x8 = 1.0 / fMass
  
• +0xC = fTurnMass
  
• +0x10 = fDragMult
  
• +0x14 = CentreOfMass.x
  
• +0x18 = CentreOfMass.y
  
• +0x1C = CentreOfMass.z
  
• +0x20 = [byte] nPercentSubmerged
  
• +0x24 = fMass * 8.0000001e-1 / nPercentSubmerged
  
• +0x28 = fTractionMultiplier
  
• +0x74 = [byte] TransmissionData.nDriveType
  
• +0x75 = [byte] TransmissionData.nEngineType
  
• +0x76 = [byte] TransmissionData.nNumberOfGears
  
• +0x7C = TransmissionData.fEngineAcceleration (Multiplied by 3.9999999e-4)
  
• +0x80 = TransmissionData.fEngineInertia
  
• +0x84 = TransmissionData.fMaxVelocity (Multiplied by 5.5555599e-3)
  
• +0x94 = fBrakeDeceleration (Multiplied by 3.9999999e-4)
  
• +0x98 = fBrakeBias
  
• +0x9C = [byte] bABS
  
• +0xA0 = fSteeringLock
  
• +0xA4 = fTractionLoss
  
• +0xA8 = fTractionBias
  
• +0xAC = fSuspensionForceLevel
  
• +0xB0 = fSuspensionDampingLevel
  
• +0xB4 = fSuspensionHighSpdComDamp
  
• +0xB8 = Suspension upper limit
  
• +0xBC= Suspension lower limit
  
• +0xC0 = Suspension bias between front and rear
  
• +0xC4 = Suspension anti-dive multiplier
  
• +0xC8 = fCollisionDamageMultiplier (multiplier not yet found)
  
• +0xCC = [hex] modelFlags
  
• +0xD0 = [hex] handlingFlags
  
• +0xD4 = fSeatOffsetDistance
  
• +0xD8 = [dword] nMonetaryValue
  
• +0xDC = [byte] Front lights
  
• +0xDD = [byte] Rear lights
  
• +0xDE = [byte] Vehicle anim group

but when I try to call a pointer 0xC2B9DC in a cheat engine, and then add 0x14 to it, it does not find anything


Please, help me  :-/

heres one example for the mass

Wow! Really working. Sorry, but where you get this addresses? (8C and BA18FC)

Ohh... This only works for the mass of the car. Can I somehow change, for example, the angle of rotation of the wheels? Or change the drive from the rear to the front

0xC2B9DC - The beginning of the Handling block

Should be easy enough to understand what I mean

Also you should also understand that every car ingame has its own ID and in case you want to change the property of any desired car you have to do the following math :

0xE0 * ID + 0xC2B9DC

I used this https://github.com/thereals0beit/m0d-s0beit-sa/blob/91cd572e728dfdbf854dfa30072bbc81ca54aaa1/src/cheat.h#L558 and calculated all the adresses

I'd rather use the pointer to the car im sitting in, due to the fact that I dont care about the handling of cars im not driving

---

Okay, 0xC2B9DC contains the handling of all the model ids!

Hmm ... Somehow it does not work. I tried this:

           //elegy model ID
0xE0 * 562 + 0xC2B9DC + 4

And it gave out just 0. Why? :c

If you tried this math inside the cheat engine then the reason why it couldn't possibly work is that it takes only hexadecimal numbers, that means you have to convert 562 to hex

Okay, I found in Google that 562 is 0x232. Now I try this:

0xE0*0x232+0xC2B9DC+0x4

And got this:

Why?
sorry for my stupidity)

Not your fault, I kinda misinformed you
You should substract 400 from Model ID to get handling.cfg ID, also that may not work for 100% but as example here's the way of changing Infernus mass

0xE0*0xB+0xC2B9DC+0x4
0xB here is 0x232 - 0x190, so I guess the final template is ([Hexadecimal MODEL ID]-0x190)*0xE0+0xC2B9DC+0x4

Thank you! It Really working!

The ids are not the model ids but in the order of the handling cfg i think

Here are the IDs
